Kalaphorura burmeisteri is a distinctive species (up to 3.1 mm in length) found under fallen branches and among leaf litter (Figs. 1 & 2). It is often recorded during the winter months and is active under snow. With the exception of records from Wensley, Yorkshire by Brown (1918), and Edinburgh by Bagnall (1937), all localities are south of a line drawn through Anglesey and The Wash. Most authors regard Kalaphorura tuberculata (Moniez, 1891) as a junior synonym of Kalaphorura burmeisteri. Kalaphorura bearei (Bagnall, 1937) (wrongly placed in this genus by Salmon (1959)) is clearly a species of Onychiurus (I have examined the holotype), but its exact identity is uncertain. The anal spines are prominent (Fig. 3), there is a vestigial furca consisting of two small bumps (Fig. 4) and the post-antennal organ consists of two rows of elongate vesicles (Fig. 5). The empodium of the foot is expanded at the base (Fig. 6) and there are two pseudocelli near the base of each antenna (Fig. 7).
